Abstract

Aim of the present study is to analyze science teacher candidates’
laboratory videos by using Many-facet Rasch model. Survey method was used in
the study. The study was conducted in 2017-2018 academic year spring semester. Rasch model’s surfaces are respectively: 9
juries, 13 science activities and 19 criteria. FACETS program was used for data
analysis. Findings reveal that laboratory video, which was coded as SA8, was
found to be the most successful and SA1 coded video was found the most
unsuccessful with respect to criteria. The simplest articles
which science teacher candidates were subjected are “introducing yourself”,
“using proper costume”, “appropriate time” and the articles for which the
science teacher candidates are constrained mostly “sound-supporting effect”,
“writing effect”, “warning for security precautions”. Jury numbered 3 or coded as J3 is “the most
lenient” and scorer numbered 2 is “the severest” when juries are sequenced from
the most lenient. Moreover, it could be said that, some of the jury members were extremely severe or
lenient against some science activities according to bias analysis.
